  1. Assume the claim was null hypothesis.  If the analysis contradicted the null about a population parameter then the alternative is supported, i.e., the claim is not supported.
    1. True                 b.   False
  2. The null hypothesis is considered correct until proven otherwise.
    1. True                 b.   False
  3. If the claim is that a population parameter is not a specific value, the particular type of problem would be considered a one-tailed test.
    1. True                 b.   False
  4. If the null hypothesis is rejected, this tells us that the alternative is absolutely true.
    1. True                 b.   False
  5. Hypothesis testing starts with an assumption that a researcher makes about a sample statistic. This assumption is called a hypothesis.
    1. True                 b.   False

Please answer True or False for the following statements: 1.) In hypothesis testing, if the null hypothesis is rejected, then the alternative or motivated hypothesis must also be rejected. 2.) Under certain conditions, binomial distributions can be approximated by normal distributions. 3.) Using a normal distribution to approximate binomial probabilities is extremely accurate, but takes an excessive amount of time and should be avoided. 4.) A bell-shaped curve is still normal, even if the mean, median, and mode are not...

In this hypothesis test, would a z test statistic be used or a t test statistic and why? z test statistic would be used as the mean is less than than 30 t test statistic would be used as the sample size is less than 30 t test statistic would be used as the standard...
